Does it have to be remote?
I keep files I care about on Owncloud, so there are 5 separate devices with regularly synced copies of everything - but all on my own disk space. Movies and music are on a single drive on a home server, but I simply back this up overnight to another drive using robocopy rather than anything clever. All my family PCs back up to the same drive (The windows devices just use file history) so they're all replicated at the same time as the movies etc.
